Fruit consumption to lower risk of cardiovascular disease

A study in China that spanned seven years and included nearly half a million participants concluded that everyday consumption of fruit decreases the risk of having cardiovascular disease by 40 per cent. Dr. Huaidong Du presented the study at the European Society of Cardiology Congress (ESC) in Barcelona.

The research involved 451,681 participants from China with no history of cardiovascular disease. Their fruit consumption habits were categorized into none, monthly, one to three days per week, four to six days per week or daily. The results showed that the risk of developing cardiovascular disease decreased by 24 to 40 per cent for those who ate fruit on a daily basis. It also lowered the participants’ blood pressure, with daily fruit consumption pointing towards a 3.4 mmHg lower systolic blood pressure and a 4.1 mmHg lower diastolic blood pressure.

Pork products infected with E.coli send 19 people to hospital

Alberta’s chief medical officer has confirmed that 100 people have become infected with E. coli from consuming raw pork products, as reported by the Canadian Press. 19 of these people have been hospitalized. Pork products from grocery store V and T Meat and Food in Calgary and meat distributor Hiep Thanh Trading in Edmonton will be investigated by the Canadian Food Inspection Agency over whether they contain E. coli 0157:H7. The two companies have been shut down.

“We’ve followed all the instructions to sanitize and sterilize everything,” V and T Meat and Food spokeswoman May Tai told the Canadian Press. “However, our facility is very clean and very spotless. We have nothing further to do. We are just waiting for the approval to reopen.”

E.coli can lead to serious health problems like kidney damage or failure, while affecting others less heavily. In the past, E.coli problems have been found more often in beef products. Alberta Health Services and the CFIA are further investigating the issue at hand.

A potassium-rich diet could lower the risk of stroke in postmenopausal women

A potassium-rich diet could lower the risk of stroke in postmenopausal women

According to a new study led by Sylvia Wassertheil-Smoller, Ph.D. of Albert Einstein College of Medicine and published in the American Heart Association’s journal Stroke, a potassium-rich diet could lower the risk of stroke in postmenopausal women. Previous studies have come to the conclusion that potassium consumption could help lower blood pressure.

The study took place over 11 years observing over 90,000 postmenopausal women between the ages of 50 and 79 and their potassium intake. While at the start of the study, none of the women had experienced a stroke, the women involved in the study with the highest potassium had a 12 per cent lower risk of stroke than those with less potassium in their diets. Patients with a normal blood pressure who were not taking medication for hypertension had a 21 per cent lower risk of stroke. For women with high blood pressure and taking medication for hypertension, having a diet high in potassium did not reduce the risk of stroke.

“Fruits and vegetables are good sources of potassium, and potassium not only lowers postmenopausal women’s risk of stroke, but also death,” Dr. Wassertheil-Smoller told CTV News. “Our findings suggest women need to eat more potassium-rich foods… Some foods high in potassium include white and sweet potatoes, bananas and white beans.”

Dr. Wassertheil-Smoller also warns that too much potassium can be dangerous for the heart. The recommended daily potassium intake is 4,700 mg, according to the U.S. Department of Agriculture.

The number of farmer's markets in Canada is rising

Calgary Co-op plans to connect consumers and local farmers by hosting pop-up farmers’ markets in the parking lots of three of its locations. The markets will feature local food producers and some of Calgary’s most popular food trucks.

According to Ken Woo, Calgary Co-op’s CEO, farmers’ markets are a different way to create a more exciting and interactive process with consumers and local producers.

“When a producer talks to you about their product and how it’s made, it’s a great story to listen to,” says Woo to Canadian Grocer. “A lot of them are very family-oriented, and local producers seem to have a flare when they talk about their product’s history.”

Calgary Co-op will have new producers come to its stores on weekends to discuss their products, and will also be tagging local produce with its origin to show consumers where the food is from.

The popularity of chaga mushroomed in 2012

 By Noa Glouberman

 

If you’re not yet selling chaga mushroom, called a “Gift from God” by Siberians and “Diamond of the Forest” by the Japanese, chances are that you’ve at least heard its promotional buzz. The popularity of this wild fungus, formed beneath the surface of a host tree (usually birch) has skyrocketed in the past year.

Terry Willard, PhD, states that his Wild Rose Chaga Super Food is now the company’s third top-selling product, and Five Mushroom Blend which contains chaga is the second to top-seller (only beneath his trademark Wild Rose detox product).

What is it?

Its crusty black mass or “conk” formation with a foamy yellow-orange interior is often called a “mushroom,” but it’s actually a fungal body that precedes the organism’s spore-forming stage.

What makes it unique?

David Wolfe, author of the new book Chaga: King of the Medicinal Mushrooms, writes, “Chaga constitutes perhaps the greatest storehouse of medicinal healing properties of any single mushroom — or any herb, for that matter.” Gregg Elias of California-based Essential Living Foods, which sells organic chaga mushroom powder, agrees: “It is so powerfully life enhancing; I take it every day.”

How is it sourced?

Wild chaga grows in Russia, Europe, the U.S. and Canada. It is harvested from living birch trees, dried and ground before being distributed. Approximately five in every 20,000 trees will grow the fungus naturally.

Is it ecologically harvested?

Willard says it is sustainable if taken in specific ways. Wild Rose gets its chaga from Siberia because it is certified organic. There, 20 per cent of the chaga is ground up and returned to the soil beneath trees that have the growth. The chaga actually has a healing effect on the tree, not killing it as some fungus does. Since the growth is so rare, trees are purposely wounded at convenient (and not detrimental) locations to grow the mushroom. It takes two to three years for the fungus to grow.

Although chaga is grown in Canada, it does not yet have organic certification, according to Willard. (His son, Yarrow Willard’s company Harmonic Arts Botanical Dispensary uses Canadian chaga in its products, but only taken from birch trees that have been chopped for firewood.)

Retailer response?

Willard, who has been promoting chaga by offering retailers his product within a tea during his lectures, says it’s the best tasting mushroom available, which increases positive response and sales. It tastes like weak coffee with a hint of wintergreen. Elias says, “It has a wonderful, mild, almost woodsy flavour, slightly smoky, that really doesn’t need any sweetener.”

Costs?

Chaga has doubled in price as an ingredient in the past year due to publicity, partly because David Wolfe’s new book increased demand, says Willard. So far, this hasn’t affected product costs, however.

Is it new?

North American interest in chaga was sparked in the 1960s, after Nobel laureate Aleksandr Solzhenitsyn wrote about its benefits in his book, Cancer Ward. It has been wild-harvested in Siberia since the 70s for anti-cancer pharmaceuticals. In China and Siberia, the mushroom has been used for thousands of years to promote longevity. There is also evidence of its use as a remedy for cancer, gastritis, ulcers and tuberculosis in 16th-century Europe.

What’s in it?

Elias points to chaga’s high levels of anti-cancerous and immune-boosting beta-glucan polysacchariudes for its immune boosting action. It also has and stress-protective adaptogens, and sterols and triterpenes that aid digestion and detoxification. The mushroom boasts vitamins, minerals and amino acids, and also takes inedible medicinal properties from its host tree (like tumour-inhibiting betulinic acid, found in birch bark) and converts them into something we can ingest.

What does it do?

Chaga has been found in scientific research to boost immunity, lower stress, balance blood-sugar and treat cancer. According to Wolfe, the mushroom may be used to soothe pain, decrease inflammation, and fight viral infections (like flu, herpes, hepatitis and HIV). It also purifies the blood and balances blood-sugar. It may delay the growth of certain tumours, promote cardiovascular health, calm the nervous system, and help lower cholesterol.

How is it sold?

It is commonly promoted in powder form, but chaga is traditionally brewed as a tea. Since its delivery system is increased with steaming, adding it to tea or coffee may actually increase its efficacy, states Willard. However, it is sold as a superfood that is added to everything from chocolate to shakes, sauces and soups.

How quickly does it work?

Elias says that the speed of chaga’s efficacy depends on several factors, the most important one being the user’s health. “I don’t know hard facts, but people who’ve tried it have told me that their mood improved almost immediately, they had more energy and even their skin cleared up in a short amount of time.”

Are there different qualities?

“Many suppliers can’t guarantee the genetics or even the purity of the mushrooms they’re selling,” says Elias, adding that retailers should look for certified organic or wild-crafted chaga with no cracked spores. “It’s important to get it in its most natural form so that all of the enzymes and metabolites that are expressed by the mushroom are maintained.”

Because it is rare, chaga can also be manmade ─ cultivated in laboratories. This is promoted to have similar antioxidant effects to its wild cousin, but companies that use the natural ingredient disagree.

Pycnogenol

Pycnogenol

Name of ingredient 

Pycnogenol (Pinus pinaster)

Applications

As one of the most versatile supplements currently in the marketplace, Pycnogenol has been extensively studied over the past 40 years. More than 280 public clinical studies and reviews have been conducted to ensure the safety and efficacy of this ingredient; to date, roughly 7,000 patients have participated in 98 clinical studies. Published findings have revealed many beneficial applications of Pycnogenol for heart and circulatory health, joint care, oral and topical skin care/beauty, cognitive function, as well as women’s health. In 2008, Pycnogenol was ranked as one of the top-selling 30 herbal dietary supplements in the U.S.

Sources/Origin

A natural plant extract, Pycnogenol derives from the bark of the maritime pine tree. These trees are native to the southwestern Mediterranean region, and largely grow along the coast of southwest France in Les Landes de Gascogne. Currently, the Landes forest is the largest maritime pine forest in Europe.

History

The maritime pine tree has often been used as a source of timber within its native regions. As a natural extract, this ingredient is used for its strong antioxidant properties. Patented under the name Pycnogenol, it has been used in Europe since the early 1970s, and was first introduced to the U.S. in 1987. Today, Horphag Research is the exclusive worldwide supplier of Pycnogenol.

Benefits

Pycnogenol has four basic and beneficial properties:

•          It is a powerful antioxidant

•          It serves as a natural anti-inflammatory

•          It selectively binds to collagen and elastin

•          It contributes to the production of vascular mediator nitric oxide (this helps to vasodilate blood vessels)

Dosage

Recommended dosage has varied depending on the scientific results of the clinical studies and reviews. As a general rule, 1 mg of Pycnogenol per kilogram of body weight is suggested for safe and effective results.

Format 

Pycnogenol can be found in several formats, including tablets, capsules, soft gels, powders, strips, shakes and drinks.

Side effects

Some people may experience minor stomach irritations, headaches, dizziness or nausea; therefore, it is recommended to take Pycnogenol with food. As a precaution, Pycnogenol should not be taken during the first three months of pregnancy. To date, no serious side effects have been reported.

Regulations

Pycnogenol has been affirmed GRAS (generally recognized as safe) for use in conventional foods and beverages. These findings, based on the evaluation of clinical safety and pre-clinical toxicology results, were conducted by an independent panel of experts. The data has been gathered from more than 70 clinical studies on healthy participants and patients with a particular pathology or dysfunction.

Current research

Current findings have revealed many additional effects of Pycnogenol. For example, new investigations published in Panminerva Medica have found Pycnogenol can help reduce the signs and symptoms of menopause. Over an eight-week period, study participants were given a daily dose of 100mg of Pycnogenol. Results indicated considerable reduction in hot flashes, mood  swings, night sweats and bloating. The study also revealed Pycnogenol can help with digestive problems and irregular heartbeat.

Another study published in Panminerva Medica found Pycnogenol to be effective in enhancing the mental performance of healthy college students. Following an eight-week trial, participants demonstrated an improvement in attention, memory and mood. The results further indicated a 17 per cent decrease in anxiety, effectively improving cognitive function.

Most recently, a clinical trial published in the January 2010 issue of Pharmacology and Physiology reported that Pycnogenol can help to reduce visible signs of aging. The clinical trial investigated 20 healthy women between 55 and 68 years of age. Over a 12-week period, participants were given 75 mg of Pycnogenol daily. The results found this natural supplement to improve the hydration, elasticity and overall appearance of skin.

Celery Seed Extract

Celery Seed Extract

Name of ingredient

Celery seed extract, known as 3-nbutylphthalide or 3nB.

Applications

• Lowering blood pressure.

• Detoxification.

• Treating rheumatism and gout.

History

The celery plant is native to the Mediterranean region, where the seeds were traditionally valued for their medicinal properties. The story about 3nB is that the father of a researcher at the University of Chicago Medical Center ate a lot of celery and discovered it was significantly reducing his blood pressure. This prompted research into 3nB and its positive effects on blood pressure, as well as rheumatism.

Sources/Origin

Seeds from the flowers of the celery plant.

Format

Tablets

Dosage

The dosage is celery extract standardized to contain 85 per cent 3nB and other celery phthalides at a dosage of 75 to 150mg twice daily.

Side effects

No side effects have been studied; however, pregnant or lactating women are recommended to not take celery seed extract. Also, according to some sources, a percentage of the population is allergic to celery seed extract.

Regulations

Celery seed extract is not listed in the Natural Health Products Ingredients Database of Health Canada. However, celery seed powder is listed as a defined organism substance and is legal. In the U.S. celery seed supplements are classified as a food by the FDA.

The Department of Justice, Canada, lists celery seed extract under regulation 8.10.011 and states it “shall be the essence, extract or flavour derived from celery seed…and shall correspond in flavouring strangth to an alcoholic solution containing not less than 0.3 per cent by volume of volative oil of celery seed.”

Current research

Research is in progress to determine what other applications celery seed extract can be used for. There is some indication it may also be useful for treating colds, arthritis, digestive disorders and liver disease.

Raspberry Ketone

Raspberry Ketone

Raspberry ketone is most known for its use in perfume, cosmetics and as a food additive, giving off a fruity odour. As of late, it has been shown to increase fatty acid oxidation and prevent elevations in body weight; this effect has only been demonstrated privately in one small human study (Ziegenfuss, 2006) that looked at metabolic rate (including fatty acid oxidation) and safety in humans, using a specific raspberry ketone raw material called Razpberi-K®. Razpberi-K is used exclusively by Nuvocare Health Sciences Inc. in Canada

and is a registered trademark of Integrity Nutraceuticals International. No other studies have been done with humans, although products containing this compound are marketed
for weight loss.

History

Red raspberries have been used for centuries in traditional medicine to treat a range of conditions and ailments. Raspberry ketones are a major aromatic compound in red raspberries, making them responsible for the smell of raspberries. Due to this, raspberry ketones have been used in cosmetics and perfumes as a scent since the 1960s.

Origin

Naturally extracted raspberry ketones exist at about 1-4 milligrams per kilogram of red raspberries. It would not be possible to eat enough raspberries to get a physiologically active dose. Because of this, naturally extracted raspberry ketones are extremely expensive, and so commercially available varieties are often synthesized in a lab.

Benefits

The three benefits raspberry ketone is known to deliver are:

• An increase in norepinephrine-induced thermogenesis (especially when taken before exercise)

• An increase in Hormone Sensitive Lipase (HSL) in fat cells, which causes fat cells to release fatty acids to be used as energy

• A decrease in fat absorption in the small intestine

Effective dosage

In the only human study conducted, 200 mg was shown to be safe. On his show, Dr. Oz recommended a dose of between 100 and 200 mg, two times daily. This is considered the ideal dosage (and preferably 200 mg before exercise) to help support weight loss when combined with diet and exercise.

Side effects

Some people experience stomach irritation if they take 400-500 mg or more of raspberry ketone at one time, so this should be avoided.

Format

Capsules

Regulations

In 1965, the U.S. Food and Drug Administration placed raspberry ketone on “generally recognized as safe” (GRAS) status. Despite the lack of research, due to raspberry ketones being extracted from fruit, they are generally considered safe.

Health Canada classified raspberry ketone as a Natural Health Product (NHP) under Schedule 1, item 2 (an isolate) of the Natural Health Products Regulations. Its non-medicinal purpose, according to Health Canada, is as a flavour enhancer.

Current research

There is only one privately conducted human study on Razpberi-K® and no public studies available yet on the effects of raspberry ketone in humans. Dr. Oz’s advice is based on two research studies involving mice that were fed high-fat diets and high doses of raspberry ketones and failed to gain as much weight as other mice on the same diet, without the raspberry ketones.

Another study also found that raspberry ketones promoted the breakdown of fat inside the fat cells to increase weight loss in mice.

Therefore, raspberry ketones have been established as body-fat-reducing in mice, and can potentiate fatty acid oxidation in humans (Razpberi-K®) yet further research using humans needs to be done to more clearly define the efficacy of raspberry ketones in humans.
